In this activity, we will be learning to divide numbers mentally.

 

Division and multiplication are the inverses of each other. 

This can be really helpful when dividing!

 

When we know a multiplication fact, we can use this to find two related division facts. 

 

example of inverse facts

 

 

Let's try an example together. 

 

Example

Write the missing number:

8 ÷ ? = 2

 

Answer

We know that 2 × 4 = 8

So, using the inverse we can say that 8 ÷ 2 = 4 and 8 ÷ 4 = 2

So the answer is

8 ÷ 4 = 2

 

Now you know how to use related facts, it's time to try some more questions like this yourself.
